Mechanical mixing stirrer

Abstract

The invention discloses a mechanical mixing stirrer, and mainly aims to provide the mechanical mixing stirrer having the advantages of high mixing uniformity degree, reliable operation, and convenient construction and installation. The mechanical mixing stirrer comprises a drive mechanism; the drive mechanism drives a stirring shaft through a transmission mechanism; the stirring shaft is of a hollow structure, is connected with a drug feeding pipe, is insertedly provided with a plurality of strip-shaped porous pipes at intervals, and is communicated with the porous pipes. The mechanical mixing stirrer enables a drug liquid to be mixed uniformly, has the advantages of decreased drug using amount, simple manufacture, flexible manufacture, and low maintenance cost, and saves power consumption.

Description

technical field [0001] The invention relates to a mechanical mixing agitator. Background technique [0002] At present, in the mixing system of water supply and drainage treatment, the methods used can be divided into hydraulic mixing and mechanical mixing. 1) Hydraulic mixing. Hydraulic mixing includes water pump mixing, tubular static mixer mixing, diffusion mixer mixing, falling water mixing and hydraulic jump mixing. Water pump mixing is to add liquid medicine to the suction pipe of the incoming water pump, and achieve the purpose of mixing through the high-speed rotation of the pump impeller. The tubular static mixer is to set a section of multi-section fixed blades in the water pipe, so that the water flow can generate vortex and cross flow in it to achieve the purpose of mixing. The diffusion mixer is to add a conical dispensing cap in front of the orifice mixer, and use the vortex and reverse flow formed by the orifice mixer to achieve the purpose of mixing. Wate...

Problems solved by technology

In order to improve the mixing effect, parameters such as the diameter, width, distance from the bottom of the pool, and the number of layers of the agitator of the paddle agitator have a large proportional relationship with the mixing pool, and the required power is large, so there are many consumables and high energy consumption.

The propulsion mixer has high efficiency, but the design and manufacture are complicated. To achieve the ideal mixing uniformity, it is often necessary to use imported products (such as Cheminier, Laining, etc.), which are expensive

[0004] Since the traditional mechanical mixing agitator and the liquid medicine dosing system are two independent parts, whether it is a paddle mixer or a pusher mixer, there is a separation between the dosing point and the agitator, resulting in high energy consumption for mixing and ideal mixing uniformity Difficulty and high cost
